In my neck of the (american) woods, it usually is “free delivery! No fees if your meal is $15 or more!” according to their ads, but then they artifically raise the menu prices in the app. A meal might cost you $12 with tax at a burger place near me, but on ubereats / doordash that same meal is $19 because they raised the menu price. That way when you go to pay, it says there was “no extra fee”.
Not to be an ass, but youre 20 so you arent one of “The Kids” anymore lmao. Youre an adult now. I think your point definitely still stands though. Im only slightly older than you and when I was in highschool virtually everyone had IG, Snapchat and Twitter. I dont talk to anyone in the highschool age bracket but I think they probably still use IG/Snap/Twitter (or X if you prefer).
